Configuration of protocols. # # # # Configuration flow of the script is as follow: # # i. Adding of Ethernet and IP within both topologies, # # ii. Ading and configuration of OSPF and LDP router over IP # # iii. Adding of Route Range behind DG of each topology # # iv. Configuring loopback address as Router ID # # v. Adding of chain DG for both topologies, act as PE router # # vi. Adding of BGP over loopback address within chained DG in both # # topologies # # vii. Adding of EVPN-VPWS EVI over BGP within both topologies # # viii. Adding of MAC cloud behind each EVPN-VPWS EVI # # ix. Configuring VPWS Service Id and service Id along with label # # value and No. of MAC pools # # # # 2. Start all protocol. # # 3. Retrieve protocol statistics. # # 4. Retrieve protocol learned info. # # 5. Configure L2-L3 traffic. # # 6. Start the L2-L3 traffic. # # 7. Retrieve L2-L3 traffic stats. # # 8. Stop L2-L3 traffic. # # 9. Stop all protocols. # ################################################################################ import os import sys import time def assignPorts(ixNet, realPort1, realPort2): chassis1 = realPort1[0] chassis2 = realPort2[0] card1 = realPort1[1] card2 = realPort2[1] port1 = realPort1[2] port2 = realPort2[2] root = ixNet.getRoot() vport1 = ixNet.add(root, 'vport') ixNet.commit() vport1 = ixNet.remapIds(vport1)[0] vport2 = ixNet.add(root, 'vport') ixNet.commit() vport2 = ixNet.remapIds(vport2)[0] chassisObj1 = ixNet.add(root + '/availableHardware', 'chassis') ixNet.setAttribute(chassisObj1, '-hostname', chassis1) ixNet.commit() chassisObj1 = ixNet.remapIds(chassisObj1)[0] if (chassis1 != chassis2): chassisObj2 = ixNet.add(root + '/availableHardware', 'chassis') ixNet.setAttribute(chassisObj2, '-hostname', chassis2) ixNet.commit() chassisObj2 = ixNet.remapIds(chassisObj2)[0] else: chassisObj2 = chassisObj1 #
